    (54) Rear wheel turning system for four-wheel-steered vehicle


    (57) A rear wheel turning system for a four-wheel-steered vehicle provided (1) with a slip control system such as an anti-skid brake system or a traction control system includes a rear wheel turning mechanism (B) which turns rear wheels (2RL,2RR) of the vehicle in response to turning of front wheels (2FL,2FR) of the vehicle (1) according to a predetermined rear wheel turning characteristic. The rear wheel turning characteristic is corrected substantially in response to initiation of operation of the slip control system, and the correction is held until a predetermined condition is satisfied after interruption of the operation of the slip control system.
